I have tried the 1200 series and they simply don't work for RAID or 
non-RAID use.  They have Sil chips which cause intermittent 
problems.  These problems are also present in other adapters that use some 
of the Sil chips.  Unfortunately the Sil chips are "hit and miss" as they 
have different versions (masks) of the same chips and some will work while 
most do not.
